To all whom t may concern.'

Be it known that I, WARDLOW M. Jnssur, a citizen of the United States, and a resident of Clinton, in the county of `Clinton and State of Iowa, have invented certain new and useful Improvements in Bottle Stoppers, of which the following is a specification.

This invention relates to bottle Stoppers7 having reference particularly to a stopper for medicine bottles.

The invention has for its objects the provision of a hygienic and simply constructed device of this character which comprises means for protecting the bottle contents and removing the same in predetermined quantities without liability of wastage.

In carrying out my invention I employ a longitudinally recessed cork having a pump fixed therein, said pump comprising means adapted for drawing liquid from the bottle and ejecting it in desired predetermined quantities, either drop by drop or in a steady stream, as hereinafter fully described and speciiically set forth in the appended claims.

Iuthe accompanying drawings forming part of this specification, Figure 1 is a longitudinal sectional view illustrating an embodiment of my improvements;

Fig. 2 is a perspective view;

' Fig. 8 is a detail view of the piston rod forming art of the pumping device;

Fig. 4 1s a perspective view of a slightly f modified form of pump cylinder; and

Fig. 5 is a fragmentary perspective view illustrating a further modification.

In the drawings 2 indicates a tapered stopper composed of cork or other suitable flexible material and having a cylindrical recess 3 extended axially therethrough. Within the recess 3 is fixed a cylinder 4 composed preferably of glass, porcelain or other suitable non-corrosive material. vSaid cylinder has an integrally formed head 5, having an annular flange 6 and a central aperture 7, of relatively small diameter, through which liquid from a bottle may be drawn into the cylinder and also discharged therefrom. Y

y Reciprocatively engaging the cylinder 4 is a plunger 8, which is fixed on the end of a stout wire rod 9, by means of stops 10 and 11 formed integral with said rod. The rod 9 is further provided with a looped finger grip 12, whereby reciprocative movement may be imparted to the plunger 8 or the cork may be drawn from the bottle.

The rod 9 may have its finger grip formed integral therewith or the outer end thereof may terminate in an eye 13, for engagement with a ring 14 constituting a linger grip, as shown in Fig. 2 of the drawings, Whereby Said ring may lie on the to-p of the cork k2-when the bottle is corked and not in use,

thus bottles containing my improved stoppers may be packed and transported in a relatively small space.

The outer wall of the cylinder 4 may be tapered, as sho-wn in Fig. 4 of the drawings7 for the purpose of retaining the cylinder fixed within the cork; or the end of the cylinder adj acent to the top of the cork may be flanged as shown at 15, Fig. 5 of the drawings.

In the operation and use of the invention, when it is desired to draw liquid from a bottle, to the neck of which the stopper is attached, it is simply necessary to draw the plunger outwardly, whereupon said plunger will suck liquid from the bottle into the cylinder 4. Then upon removing the cork from the bottle the liquid may be ejected through the aperture 7, in drops, if desirable, or in quantities to suit requirements and any surplusage of liquid remaining in the cylinder may be returned to the bottle, thus obviating any wastage.

I do not wish to be understood as conining myself to the specific details of mere mechanical construction of the elements of my improvements as herein shown and described, as under the spirit of my invention I believe that I am entitled to employ such minor variations of details as may rightly fall under the scope of the appended claims.

Having thus described my invention, what I claim as new and desireto secure by Letters Patent, is:

1. A bottle stopper comprising a flexible cork, a cylinder positioned within said cork having its lower end exposed and having an opening therein, a piston within said cylinder, a piston rod attached to said piston and extending outwardly thru said cork and a finger engaging member secured to the outer end of said piston rod.

2. A bottle stopper comprising a iexible cork, having a cavity extending from the bottom thereof inwardly into the same, a

cylinder insertable Within said cavity, means formed on Said cylinder for closing said cylinder and cavity having an aperture formed therein, a piston movable Within said cylinder, a piston rod secured to said piston and extending through the top of said cork and Ineans on the end oit said piston rod for reciprocating the same.

3. A bottle stopper comprising a flexible cork, a cylinder Within said cork, said cylinder having a closed head and a contracted aperture, and a reciprocative plunger Within said cylinder, and means for imparting reciprocative movement to said plunger, Whereby liquid may be drawn into and ejected from said cylinder.

4;. In a bottle stopper, thecoinbination of a recessed cork, a cylinder Within said cork, and a reciprocative plunger Within said cylinder, said cylinder' having a closed head With a contracted aperture therethrough,

said plunger having an extended rod, and a finger grip on the outer end of said rod.

5. In a bottle stopper, the combination of a recessed cork, a cylinder within said cork, and a reciprocative plunger Within said cylinder, said cylinder having a flanged head and a contracted aperture therethrough, said plunger having an extended rod, and a hirged finger grip on the outer end of said roc.

6. A bottle stopper having a recess formed therein, a piston within said recess adapted to be operated to draw Huid int-o said recess and an inlet and outlet passageway communicating with said recess at the inner end of said stopper.

Signed at Clinton, in the county of Clinton and State of Iowa, this 16th day of July, A. D. 1921.
